Inserts not included.  Insert numbers are put with "xx", leaving for the user to decide eighter "02" or "04" to use for the specific purpose.
BJ2020-L is to be inserted in the cross tool hole.  Therefore, the boring depth is head length (83 mm) plus insert bite (1 mm), a total
of 84 mm only.  To reach a longer depth, a so-called "BT Bar" must be placed below the head.  When ordering, please specify the
length of this BT Bar.
